Answer: 48560
Step-by-step explanation:
The correct answer to this question is this one: "D. 11.474"
your calculator probably doesn't do "secant". But sec is 1/cos
so do cos(85) (in degree mode, not radian mode)
then "invert it": 1 / ANS or x^-1 if you have that key
or type
1/cos(85 degrees)= <span>11.4737</span>
The answer is x= -10. To get this answer you have to simplify both sides of the equation, distribute, and combine the like terms. The second step is to add 15/2x to both sides. Step 3 is to subtract 72 from both sides, then divide both sides by 3
